Abstract
An ancillary tool for fitting a humeral component of a total or partial elbow prosthesis, comprising a guiding tool (30) for boring a humeral trochlea (T) along a geometric axis (X-X′) of bend of a joint to be equipped with said prosthesis. The guiding tool (30) includes a stirrup element (31) and means (32b, 33b) for securing said stirrup element on the humeral trochlea (T) so that said guiding tool defines a guiding zone that is aligned in the geometric axis of bend for the introduction (F1) of a drill (40), a punch or the like, in the humeral trochlea (T) along said geometric axis of bend. This ancillary tool also comprises at least one stepped template (701, 702, 703) for determining an anterior offset of said geometric axis of bend (X-X′) with respect to a humeral diaphyseal axis (Y-Y′).
